Spin spectroscopy of a hybrid superconducting nanowire using side-coupled quantum dots

We investigate superconducting hybrid nanowires defined by patterned gates on a two-dimensional heterostructure of InAs and Al, with lateral quantum dots operating as single-level spectrometers along the side of the nanowire. Applying magnetic field along the wire axis spin splits dot levels, providing spin-resolved spectroscopy. We investigate spin and charge polarizations of subgap states in the nanowire and their evolution with magnetic field and gate voltage.
